Dear Chris,
Thank you for your help. I did comment and added my public static IP
like the following:
listen-on { 202.x.x.x; }; # My Static IP
Now when I do from my local PC:
dig yahoo.com @202.x.x.x , I can do DNS lookups.
But when I try doing that from another computer on my network, I can't
do any DNS lookups.
Is that anything that I miss?
